Australia has progressed to the Trophy Final at the World Sevens Series in Paris following a 14-12 win over Wales in the semi-final.
In a fairly even contest it was a penalty try and a yellow card which made the difference in the end.
The Aussies were the first to get on the scoreboard after five minutes of play with a try to 18-year-old Dylan Pietsch.
Owen Jenkins answered in kind and had Wales trailing by just two points at the break, Australia up 7-5.
Lachie Anderson again powered to the line but looked to have had the ball held up in a tackle.
In a major ruling, the referee awarded a penalty try to Australia.
When Stefan Andrews was sent to the sin bin, the task became that much harder for Wales to close the gap with time running out.
Lloyd Evans scored a last minute try, but the conversion was unsuccessful and Australia held on for a 14-12 victory.
The Aussies will meet Argentina in the Trophy Final after the Puma Sevens defeated Singapore champions Canada by one just point in the other semi-final.
Earlier Australia had defeated Japan 28-19 in the Trophy quarter-final.
The Aussies had four try scorers, all from among the young guns impressing this season.
While Japan opened the scoring, Australia quickly found some of the rhythm and application which had been absent in play on Day One.
First half tries to Simon Kennewell and Tim Anstee gave the Aussies a 14-5 lead at half-time.
The tries flowed in the second half with both teams taking turns to put two each on the board through Kameli Soejima, Liam McNamara, Naoki Motomura and Lachie Anderson.
Anderson’s try was another display of strength and determination.
With the score at 21-19, the contest was tight until Anderson pushed to the line under heavy tackle pressure to score Australia’s fourth and seal the win.
